MILK CONSUMPTION AND CANCER INCIDENCE - A NORWEGIAN PROSPECTIVE-STUDY

Relationships between milk intake and cancer incidence were investigated after llj years of follow-up of 15, 914 individuals. A diagnosis of cancer was made in a total of 1, 422 individuals. No association was established with total cancer incidence, in analyses adjusted for sex, age and residential characteristics. However, a strong positive association with milk consumption was observed for cancers of the lymphatic organs (odds ratio 3. 4 for ^ 2 glasses per day vs <1; 95% confidence interval 1. 4-8. 2). An inverse association was found for cancer of the bladder. Kidney cancer and cancers of the female reproductive organs (except the uterine cervix) showed weak positive associations with milk intake. © Macmillan Press Ltd., 1990.
